NESTING SITE at Bodega Head shows a sandy cliff dotted with the homes of solitary bees. They include Anthophora bomboides stanfordiana (faux bumble bee), which builds turrets and the Colletes fulgidus longiplumosus, which shares the same cliff faces but does not build turrets, according to native pollinator specialist Robbin Thorp of UC Davis.
